  • Patent number: 7750951
    Abstract: An image sensor repeatedly receives a light from an object through a lens and generates images of the object. A differential image generating unit generates a differential image from at least two images. A detector detects a change cycle or an intensity of an external light. An evaluation unit evaluates an influence of the external light and derives an optimal timing in which a minimum influence of the external light is attained. A controller controls a timing of receiving the light of the image sensor, depending upon the optimal timing derived by the evaluation unit, and repeatedly synchronizes a term of two timings with the change cycle of the external light by shifting the term into the change cycle by a unit of predetermined phase difference.

  • Publication number: 20080291292
    Abstract: An image input apparatus. A detection section detects a change cycle of an intensity of an external light inputted to a camera. A timing control section synchronizes the change cycle of the intensity of the external light with a plurality of input timings of the camera by changing a phase difference in order. An evaluation section compares each storage quantity of the external light inputted to the camera at the plurality of input timings synchronized by the timing control section for each phase difference. A selection section selects the phase difference whose difference of the storage quantities of the external light is smallest from all phase difference changed by the timing control section.

  • Patent number: 7453511
    Abstract: An area image sensor outputs the difference between charges received by light-receiving cells arranged in an array pattern. A system controller generates a timing signal for generating a pulse or modulation signal. A control signal generator generates a control signal for separately controlling the light-receiving timings of the light-receiving cells of the area image sensor on the basis of the timing signal from the system controller. A light emitting controller controls a light source to generate light, the intensity of which changes on the basis of the timing signal from the system controller. A reflected light image processor extracts a reflected image of an object from the difference outputted from the area image sensor.

  • Publication number: 20060146175
    Abstract: An image capture module and an image capture apparatus for inputting shape of an object in three dimensional space, including a light emitting section which emits light to the object for reflection by the object and imaging of reflected light on a photo-receiving plane of a reflected light image detecting section via an image capture optical system. The reflected light image detecting section detects a reflected light image indicative of a distribution of intensity of the reflected light. The light may be irradiated evenly to the object and the shape of the object may be detected correctly even if the object has irregularity by disposing the light emitting section closely to the image capture optical system. The object may be illuminated evenly by the light from a light emitting section having plural light emitting elements by disposing the light emitting elements symmetrically about the image capture optical system.

  • Patent number: 6549909
    Abstract: An information processing apparatus is connected to a plurality of application devices. A memory section in the information processing apparatus stores, by unit of object corresponding to the application equipment, an input data type for each object and output data type for each object. The user indicates a first object as a serving side object and a second object as a receiving side object from among the plurality of the objects through an indication section. A retrieval section retrieves a third object whose input data type is the output data type of the first object and whose output data type is the input data type of the second object from the memory section, if the output data type of the first object is different from the input data type of the second object. A control section assigns the third object between the first object and the second object as a relay object.

  • Patent number: 6360003
    Abstract: When the computed velocity of barycenter of image data, acquired based on initial values of image capturing parameters, is greater than a specified value, an image capturing timing is set quicker than an initial value and a resolution of image data to be captured is reduced. When the velocity of barycenter is smaller than the specified value, the resolution of image data to be captured is set higher than an initial value and the image capturing timing is set slower than the initial value.
